1. Trellis systems, rootstocks and season influence on the phenolic composition of ‘Chenin Blanc’ grape
ABSTRACT: The biosynthesis of phenolic compounds might be influenced by environmental factors, such as solar radiation, temperature and relative air humidity, and production system. Some components of the production system, particularly the trellis system and rootstock, might change the phenolic composition of grapes due to microclimate of the cultivation re

2. Obtaining an Optical Trap Type Surface by Plasma Electrolytic Oxidation
High performance solar collectors are those with high selectivity surfaces, high solar radiation absorption and that do not thermally reemit to the external environment. Strategies to enhance this performance might involve surface porosity modification. In this work, a plasma treatment technique called plasma electrolytic oxidation (PEO) has been tested to p

3. Microclima e produção de tomate tipo cereja em ambientes protegidos com diferentes coberturas plásticas / Microclimate and cherry tomato production in greenhouses with different plastic covers
In the regions where solar energy is very intense and temperatures are high, the tomato growers use to reduce the incoming solar radiation inside the greenhouses, aiming to promote the temperature reduction, mainly by installing aluminated shading screens inside. However, the use of such covers promotes an intense reduction of the photosynthetic active radia

4. Uso de estufa agrícola para secagem e higienização de lodo de esgoto. / Use of greenhouse to dry and hygienization of the sewage sludge.
This research aimed at assessing the dry and hygienization in a greenhouse excess of the activated sludge generated in Wastewater Treatment Plants that treats domestic sewage, located in the Metropolitan Region of the Great Vitória, Espírito Santo, and from the results, estimate the area and the cost of investment required for installation from the greenho

5. Atmospheric patterns associated with concentrations of tropospheric ozone in the metropolitan region of Sao Paulo / Padrões atmofésricos associados a concentrações de ozônio troposférico na região metropolitana de São Paulo
In the past few years, tropospheric ozone has been noticed to exceed the states environmental agency (CETESB) air quality standards more than any other air pollutant in the Sao Paulo Metropolitan Area (SPMA), Brazil. Its assumed that different atmospheric patterns are responsible for different impacts on ozone concentrations, due to already known phenomena c

6. Carreador lipÃdico nanoestruturado à base de cera de carnaÃba: desenvolvimento, caracterizaÃÃo e uso na encapsulaÃÃo de benzofenona-3
Solid lipid nanoparticles made of pure lipids (SLN) or a mixture of solid and liquid lipids (NLC) have been proposed as a category of carriers for cosmetic ingredients of current and growing interest due to a number of advantages compared to conventional formulations. Natural waxes are considered lipid matrices of great potential for the production of topica

7. Relação sol-terra estudada através de anéis de crescimento de coníferas do holoceno recente e do triássico / Sun-earth relationship studied by tree growth rings in conifers from holocene and triassic
The study of the Sun and of its energy flux variations is recent and fully experimental. For this reason , if is very important develop studies in order to understand the past and predict the future using natural records at the Earth surface to monitor solar variations and their effects on climate. The studies about the Sun s variations and Sun-Earth-Climate

8. Relação sol-terra estudada através de anéis de crescimento de coníferas do holoceno recente e do triássico / Sun-earth relationship studied by tree growth rings in conifers from holocene and triassic
O estudo do Sol e das variações de seu fluxo de energia é inteiramente experimental e também muito recente, o que restringe muito a compreensão de seus efeitos sobre o clima do planeta e sua possível predição para o futuro. Assim torna-se necessário um monitoramento indireto das variações solares e de outros fenômenos geofísicos em uma escala de

10. Comportamento termico de coberturas de fibrocimento em Campinas, SP : aplicação de tecnicas passivas / Thermal behavior of fiber-cement roofing in Campinas, SP : application of passive cooling
In Brazil, the tropical climate is predominant in most of regions. Roofing is the building component with the highest exposition to direct solar radiation. The challenge for researchers and designers is to achieve cornfort in the built environrnent and to contribute to energy saving, proposing roofing systems with good thermal insulation, and consequently le

11. Balanço de radiação, energia e fluxo de CO2 em ecossistema de manguezal na Amazônia / Radiation and energy balance and fluxes of CO2 in a Amazon mangrove ecosystem
This work use the longest series of continuous meteorological data and fluxes measurements of CO2, sensible heat and latent heat made in Amazon mangrove ecosystem. The series used in this study corresponds to the period of November, 2002 to August, 2003. The meteorological data were collected using an EDISOL system based on the hedí covariance technique. Th

12. VariaÃÃo espacial e temporal da comunidade microfitoplÃnctÃnica em ecossistemas costeiros localizados no litoral sul de Pernambuco, Nordeste do Brasil
The coastal marine environment shows a strong ocean- continent-atmosphere interaction and for that reason is considered extremely complex from the biological point of view due to the influence of many systems, so it can be characterized as one of the most fertile and dynamic of the hydrosphere. The estuarine complex (Ilhetas and Mamucaba rivers) and the Tama
